Cosmobet sets clear rules for every bonus to keep offers transparent for UK players. Review the points below before you opt in to any promotion.
Cosmobet Rewards Club tracks your activity across the sportsbook and casino. You earn 1 point for every GBP 10 wagered on sports and 1 point for every GBP 20 staked in the casino. Points accumulate automatically and move you through five tiers: Bronze, Silver, Gold, Platinum and VIP.
Reaching Silver at 500 points adds a 5% weekly cashback on net losses. Gold starts at 2,000 points and raises cashback to 7.5%, plus priority withdrawal processing within 24 hours. Platinum, from 5,000 points, includes a monthly bonus of GBP 25 and entry to exclusive free spin drops. VIP status, by invitation from 15,000 points, assigns a dedicated account manager, custom deposit limits and invitations to UK sporting events.
Points convert into bonus funds at a rate of 100 points to GBP 1, redeemable from your account dashboard at any tier. Check your tier progress and point balance under the Rewards tab at any time.
Cosmobet support agents answer promotion questions around the clock, every day of the year. Reach the team through any of the channels below for help with bonus codes, wagering progress or eligibility.
